The WR Egglayer is very useful when running a wolfling run. It produce Norn, Grendel and Ettin eggs, but only enough to make sure that there are two of each species and gender. For example, if there was only one female norn but three male norns, it would create another female norn egg, but no male norn eggs. The WR Egglayer was made by Marcus K. and can be downloaded at Mummy's Creatures.
